IMPROVEMENT IN DENTAL SPITTOONS.

Specification forming part of Letters Patent No. 197,977, dated December11, 1877; application filed March 30, 1877'.

To all whom it may concern:

Be it knownthat I, WM. M. REYNOLDS, of the 'city of New York, county andState of New York, have invented certain new and useful Improvements inSpittoons for Dental Purposes, of which the following is aspecification:

This invention consists of certain improvements in spittoons for dentalpurposes, and relates to that class of spittoons which are secured tothe side of the operating-chair. The spittoon proper is supported in agimbal, and is weighted at the lower part, so that it always remainslevel in whatever position the chair may be placed, the outer bearingsof the gimbalare extended from the upper part of a rod, which fits intoa tube with sufficient friction, so that the spittoon will remain in anyhorizontal position in which-it may be placed. The tube passes throughsockets pro vided therefor in a bracket, which is rigidly secured to thechair, and it is free to move up and down therein, but is held at anydesired height by a screw clamping the top socket thereon. From thebottom of the spittoon extends a flexible pipe, which conveys the wasteto an appropriate receptacle therefor; or the pipe may pass throughthefloor and be con nected directly to the waste-pipe. The bottom of thespittoon is also provided with a cock, which is attached to thewater-faucet by a flexible pipe when it is desired to wash out thespittoon, the cock being turned off and the pipe removed when not soused. 1

But to describe my invention more particularly, I will refer to theaccompanying drawings, forming part of this specification, in which-Figure l is a side elevation of chair with my improved spittoon securedthereto. Fig. 2 is a plan view of the same; and Fig. 3 is an enlargedview, showing a vertical section of the'spittoon and supporting-bracket.

a represents the adjustable seat of a chair, and b the back. The seat issecured to the legs a of the chair by hinges, and is held at any desiredangle by the bar and pin (1. To one side of the seat a. is fastened thebracket 0, which projects upward, and is provided with two sockets, eand 0 The upper socket, e, is

split, and through the sides of it passes a thumb-screw, by means ofwhich the .socket is clamped on the hollow shaft f, thus securely holding it at any desired height. In the upper end of the hollow shaft f is arod, 9, the friction between theshaft and the rod being such that therod will maintain any position in which it may be placed. The rod 9, atits upper end, is provided with a bifurcated arm or bracket, h, betweenthe ends of which is diametrically pivoted the ring *5. The ring '1; isprovided with two pivot-screws, z" 41, at right angles to the pivots bywhich it is supported, and these pivot-screws i 2" support the body lofthe spittoon, which is made of metal, the receiver m being made of glassor other suitable material. To the center of the bottom of the body 1 isattached the flexible dischargepipe n, and off on one side is shownacock, 0, and part of a pipe, 19, the object of which is to pass waterthrough the spittoon from the water-faucet when it is desired to wash itout. Instead of the cock 0, a plug or cap may be used to cover theopening when the spittoon is in use.

It is obvious, from the construction of the spittoon as just described,that it may be adjusted to any required position, and drawn to and bythe patient using it, and then pushed out of the way.

Having now described my invention, what I claim, and desire to secure byLetters Patent is-- 1 With a spittoon for dental purposes, thecombination of the gimbal h z, substantially as hereinbefore set forth.

2. The combination of the spittoon lm and flexible discharge-pipe a,substantially as and for the purposes hereinbefore set forth.

3. In combination, the spittoon l m, gimbal h 6, rod g, hollow shaft f,and bracket 6, all constructed and operating substantially ashereinbefore set forth.

' 4. The adjustable spittoon l m, in combination with the cock 0 andpipe n, as and for the purposes hereinbefore set forth.

, WM. M. REYNOLDS.
